# Development and production data separation

The development workspace is `/home/umbra/src/UmbraTrans`. Development-only
state belongs below `.local/data/development` and is ignored by Git.

Production PostgreSQL, backup, and service paths must not be used by the
development application. In particular:

- Development configuration uses `UMBRA_ENV=development`.
- Development data is local to the workspace and is not a PostgreSQL data directory.
- Production database access, logical backups, and service credentials remain
  separate operator-managed paths.
- No live PostgreSQL data directory or running SQLite database is copied as a backup.
- Backup and mailbox locations on NAS2 require a separately confirmed mount and
  permission check.

This document describes boundaries only; it contains no credentials or tokens.
